Keeping the joints in good condition

Good habits help new joints last longer. A few tips:

  • Act on a lifting corner straight away
  • Keep bleach and abrasives off the bead
  • Report a tray that rocks or a worktop that lifts
  • Get the cause of a repeat leak found before resealing

Do not let anyone seal over it later. Over-sealing is how many remedial jobs start.

Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.

Remedial sealant for homes and businesses in Maldon

If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have pictures when you phone 0345 464 0079 or drop us an email, along with when it was last resealed. We work on expansion joints, failed movement joints and shrunken worktop sealant, and people most often call us about dark patches showing through the sealant and gaps opening along the back of the worktop.

Around Maldon, it’s mostly busy family bathrooms and kitchens, which is hard on sealant and grout. The usual signs are mould in the bead, gaps by the sink and grout that’s cracked or stained.

The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

What sealant work can’t fix

We’ll always be straight with you, so here’s what new sealant won’t do:

  • Cracks in the fitting rather than the joint
  • Water damage behind tiles that needs a tiler
  • Sealant in an older building that needs testing for asbestos first

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

Joints and surfaces we work on

  • Shrunken worktop sealant
  • Botched or over-sealed joints
  • Mouldy bath & shower sealant
  • Expansion joints
  • Failed movement joints
  • Leaking tray & enclosure joints

What happens if it’s left?

A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. In a family home in Maldon, a failed seal around a bath or a frame lets water into places you can’t see, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.

What it costs depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

Why us?

  • Tidy, careful work
  • Colour agreed with you before work begins
  • Anti-fungal silicone where joints get wet
  • A sealant colour to suit the surroundings

Read what affects the cost or our reviews.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

The process

On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied, including the tidy-up. A visit in Maldon needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Each layer is cut out and the residue cleaned off.
  3. We treat any mould and dry the joint thoroughly.
  4. We reseal with a product suited to the joint, backed where needed.
  5. The joint is tooled and you are told about anything else we found.

Before we arrive

  • Clear the area around the work
  • For indoor joints, keep the area dry beforehand if you can
  • Mention if the joints have been sealed before

Related advice

Common problems we fix in Maldon

Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.

Common reasons people contact us are:

  • Sealant applied over old sealant that has lifted
  • Repeat leaks from the same joint
  • Worktop sealant that has shrunk and split
  • Thick, messy sealant smeared over tiles

Homes close to Church of St Mary include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
